Part A:
Given that i<span>n
a population of 210 women, the heights of the women are normally
distributed with a mean of 64.4 inches and a standard deviation of 2.9
inches.
If 36 women are selected at random, the mean of the sample is estimated by the mean of the population.
Thefore, the mean is given by:

Part B:
The standard deviation using the finite population factor is given by:

Answer:
sin(3x) = sin(x + 2x)
= sinx cos(2x) + cosx sin(2x)
= sinx [1 - 2sin2x] + cosx [2sinxcosx]
= sinx - 2sin3x + 2cos2xsinx
Answer: The correct answer should be 7.6128
If you do the problem correctly, you will get an answer of 7.6128. This is because there are 4 decimals places in the numbers that are being multiplied. This means that there will be 4 decimal places in the answer. If you have her work, we can find the mistake. It is probably that she counted the wrong number of places.
